/* Adjustments and additions to the signal number constants for
|
|
Linux/HPPA. These values were originally chosen for HP/UX
|

compatibility, but were renumbered as of kernel 3.17 and glibc 2.21
|
|
to accommodate software (notably systemd) that assumed at least 29
|
|
real-time signal numbers would be available. SIGEMT and SIGLOST
|
|
were removed, and the values of SIGSTKFLT, SIGXCPU, XIGXFSZ, and

SIGSYS were changed, enabling __SIGRTMIN to be 32. */
